Unfortunately, it is just a momentarily dream for many people for several reasons. First, your boss will never allow you to make such place because he or she would feel inferior in ego and personality. Second, your colleguaes will be very jeaulous and begin to complain because they are actually your enemies in reality. Third, people would annoy you saying you don't work at all, because at many places creativity is punished instead of rewarding. Did I say much?
